FandangoNow UHD quality?

[gregr]

Sorry if there's already a thread for this - I searched for a while, and couldn't find anything.

I was thinking about buying some UHD movies on FN for the first time. How is the quality there, compared to e.g. iTunes? The movies I want aren't available on iTunes or elsewhere in UHD, so it's not like I can compare them directly - but I'm hoping someone here has a general feel for how the 4K movies from FN are looking?

I think I'll be streaming them from the FN app on a LG OLED, which seems to be the only version of their app I have that supports 4K streaming...

Thanks!
