Yes, like Lucky, Orwo and Harman colour film put price pressure on Portra and Ektar. All those new experimental films are priced higher (some even significantly higher) than lower end Kodak films (which, in addition, are technically much better).
I think you are not understanding it completely.
Harman Phoenix is still under an experimental phase, it is likely that they still haven't created a profit from their film.
Lucky Color Film is already cheaper than Kodak ColorPlus, at least in china.
People who want a color neg film can choose between Ektar, Portra, and the cheaper Gold and Colorplus. So, whoever is price conscious, can choose Colorplus, Lucky, etc.
However, people who want to shoot E6 film, only have Ektachrome and Provia available. There is no budget alternative. So there is a big oportunity to disrupt the market there. Color Slide film has a chance to become trendy again as soon as it gets down to reasonable prices.
30 years ago I used to buy Tura Chrome 100, E6 slide film, simply because it was significantly cheaper than buying Fuji Sensia, which itself was cheaper than Provia and Astia. Many years ago, Scotch Chrome 100 (made by Ferrania) was available to fill specifically that market need.
