Agfa Avichrome had the emulsion-formula that was used in the RSXII from the 90s. And indeed at some rebranded films (Rollei Chrome CR 200) there was reported a yellow hue.
From my point this is a very very special issue with Agfa chromes. If you for example remember the extreme high priced Agfa professional cromes (in that silver package wich was new at the late 70th).
It was more expensive in comparison to Kodak E6 professional films at this time. In Europe Agfa had obviously more reputation in comparison (caused from a gerneration of professional photographers who started their carrier within the 50th).
I can't say (to expensive to that time) so I have no experience with the Generation RS and RSX of Agfa chromes. But they were obviously not bad to that time far behind in comparison (Fuji had no reputation from professionals during the 70th) .
Also amatheuric chromes like CT18 were real nice Agfa Films and absolut cheap in comparison to other brands. CT18 first generation wasn't E6 if I remember correct.
Coming to OP's question. There is a Berlin based photographer who swear about the characteristics of
the RSX II ISO 200 (wich is real grainy at ISO 200 by the way) she used this emulsion because of its special colors. She had frozen around 1000 Films of the last batches because she want to proceed with that emulsion the next coming decades.Perhaps the Op had heard from other sources out of the net that the original Agfa Chromes had nice colors (indeed there is a difference from LOOK and characteristics to modern Fuji E6 and Ektachromes).
I would state the problem is from the date of production. The origin Agfa CT100 Precisas are much less stabile in comparison to each Kodak or Fuji E6 if the Films are expired.
But the main difference is : If you got a brand new fresh Precisa 100, RSX, RSXII or what ever from Agfa and this Film is emidiately couled or freezed (freezed in regard of the longer term use).
You should have real original colors. The fresh Agfas had an expiration guarantee of around two years.
The professional Agfa chromes you got just couled in your professionell store.
The amatheuric Agfachromes should hold for more than 2 years after fresh production there origin characteristics because that was the workflow of amatheuric photograpers (Films remaining in the camera over months).
But from my experience 10 Agfa CT100 (wich haven't seen a couled storage at me) came oute of a 10 Film box summer 1999. Some remaining ones exposed 2001 and developed (no it wasn't the lab) showes a greenish cast wich was such extreme I had never seen before within 25 years.
I checked the expiration date and noticed : OK in 2001 the film out of this box are expired (but just around some month) So my experience with original CT 100 is the amatheuric Agfachromes are within expiration guarantee to shot better you should use it max. 1/2 year before expiration.
(Without couled storage).
So it is all in regard of storage condition of this long discontinued Agfa Films.
The Problem with RSXII is the Agfa bankropcy. Some month after Agfa stopped production a real mass of last batches RSXII came to retailers. They offered nice prices and so this 135-36 Films came close to sold out. Very few were remaining an pricing increased to the "very last Agfa RSXII in 35mm".
But there have been also RSXII in 120 and the demand on 120 Films to that time came much more less. So RSXII were still avaible 1 year after all 35mm of that professional Agfa Chrome were sold out Worldwide.
Later a real mass of " original Agfa produced" RSXII with production dates (expired 06/2006 /082006)
in 120 entered the marked. Also some masterrolls of that emulsion.
Here is the problem with the yellow cast of the RSXII Films. Theese Films were damaged caused from insufficient storage. They seamed to be stored not in a couled condition the were stored in a heated condition. If one imagine from what mysterious sources they came they perhaps were stored in a truck some weeks in summer.
So also Rollei got some masterrolls of bad (damged condition) to that time (without knowing).
Their CR 200 of the first realease was with a yellow cast I remember from 80% of my chromes later
Rollei solved this Problem. I guess a nice amound of cheap masterols Rollei gave into trash.
Last conclusion RSX and RSXII with expiration dates 2004 and before are nice Films and if they are stored well (freezed) you may see nice colors more than an decade after expiration.
But the Films with that expiration and production dates are still not existing on the marked.
Within some exeption remember the Berlin based photographer.
The same is with all 35mm RSXII (but they were sold out short after Agfa stopped production)
What you might will get today (and the Op mentioned the dates I gave too) is stuff were we shout say
"HANDS OFF"
