HBO Max 4K Ultimate Plan...No Options???

As many others have noted, the situation with the HBO Max change is awful.  We, without any warning, lost all our 4K...Dolby Vision, Atmos, etc.  So we can see all these movies, series, are offered with all that but we cannot actually WATCH them in 4K.  As all streamers are [EDITED: Language] us over (like Prime now adding ads, etc), we see HBO doing the same and forcing us to pay more for 4K.  However, why is there no option for us to just pay for it through xfinity, like we would with (for now) Netflix??  Are you guys working this out?  Any deal/change coming anytime soon?  There was no communication on this at all from xfinity, and there has been nothing since, other than just replies saying you do not have the Ultimate Plan.  The people asking about this all have 4K tvs, and want to be able to actually use that functionality.  So if it comes down to having to choose, then most will end up canceling their premiums with xfinity and then going direct with the streamers so we can get our 4K back.  I am about to do exactly that, which means breaking up my grandfathered package....which means getting rid of all my premiums and buying direct through the streamers.  Xfinity will lose that revenue, as I imagine will happen among thousands of other customers.  So, again, is there any plan (soon) for xfinity to offer the upgrade option for the Ultimate plan for HBO Max (sorry, I cannot just call it Max, too confusing with Cinemax)?
