This must be it. It could be mistaken for grain, but it is not, because it also shows on an entirely unexposed and undeveloped film that has been through a sequence of "alkaline solution-wash-acidic fixer". It is also not a typical reticulation, as it is much finer. Since it shows on a 120 film that is sealed from air for the most of its useful life, it should not be caused by a noxious vapor. The real problem is that its appearance is variable. If you can get your hands on a 400 ASA film which is past expiration date and do not expose and develop it, just cycle through solutions as above, you should see it in its most basic form.
TMAX 400 batch number 159 is the first with new backing paper - referring to a recent update from John Sexton.Batch 0155 001, expiration 05/2019.
I thought the backing paper issue was limited to print-through of the backing paper numbers, and didn't cause any mottling?

Yours, being 0155 may not have benefited from the change.
Update 2:
I contacted Kodak, and thankfully there was no quibbling. They have said they will send me two pro-packs of TMY-2 from the latest batch with the new backing paper. Hopefully these will not exhibit the problem.
I shot my first rolls with the shiny backing paper recently with no issues and will look forward to hearing what you find when you try it out. Please share when you do.

TMax 0159 and Tri-X 1001.What batch were they from btw?
I have received the two pro-packs and they are from batch 158 (expiry 07/2020). However, according to @Bill Burk the first batch with the new paper is 159, so I'm now wondering if I've been fobbed off with more film which will have the same problems as before...
TMax 0159 and Tri-X 1001.
Does it actually have the new paper? You should see and feel a difference - it's shiny and "plasticky".Thanks.
So, I'm back to uncertainty again with the replacement film. I know I shouldn't really complain as it's free film after all, but I specifically asked for replacement packs with the new backing paper...

The batch numbers for the newest paper differ between the different films - T-Max 100, T-Max 400 and Tri-X. If I were you, I would get back to Kodak Alaris and ask them to confirm that they sent the right film.What batch were they from btw?

I just processed five rolls of TMY 120 and had the same effect as the OP. All five roll useless. I don't shoot a lot of 120, so that represents a year of work. It is not worth the time and effort to make silver images if the film is bad.
I think I'm going to start processing a test sheet or roll for ever batch of film I purchase before engaging in a project.
I checked, and no, it's the old type

This is certainly an appropriate procedure. I've pretty much avoided the Tmax flavors of Kodak in 120, but so far had good experience with even the older possibly questionable batches of 400TX. At any rate, I am awaiting receipt of a new order of 400TX from B&H and will certainly try a roll before I go trundling off to Europe in April. I also bought more Ilford HP5 Plus. When I did my big cross-USA excursion in 2016 I alternated between those two films, finding them pretty much interchangeable for my typical use, and figured I was bound to return with something! Thankfully back then all were fine.I think I'm going to start processing a test sheet or roll for ever batch of film I purchase before engaging in a project.
The original box is gone, but I bought two 5-packs at the same time. Bottom of the remaining 5-pack box indicates "08/2019" with numerals "0156 001"Was that fresh film?

It was not free. You paid for it with by buying that defective film. (I'm assuming that it was defective.)
