After a couple of weeks of research & thinking, and various posts here, I need to now make a decision, and seeking final bits of advice.
Currently, I'm using a 55" FHD IPS with my Mac mini as the hub for streaming (Netflix, Youtube, and movies from Apple TV) and music (USB Dac to Audiolab amp to KEF Q150). The TV is also used for some browsing and office work, and occasional gaming. Viewing distance is 8 feet (sofa is centered and 9 feet wide), TV is on its stand on a 2 feet high console. There is full height window on one side - no direct sunlight, but plenty of ambient light, and even at night we don't like watching in pitch dark (we always keep some of our lights on)
With the upgrade to a 65" 950H or A8H we're hoping to get a bit of gain everywhere.. bigger size, 4K support for our streaming, better contrast and HDR experience for movies, a bit less usage of our Mac mini as a hub (i.e. direct control of streaming) via android TV. By and large, our biggest use case remains day-time or evening time watching of streaming shows in Netflix and YouTube.
While initially I was locked into A8H (price difference in my region is around 800$ (2300 vs 3100).. despite the higher price, I'm now thinking overall 950H might be a better fit for me, since the better blacks of A8H aren't really critical as I feel 950H will already be a huge upgrade... and I don't watch in pitch dark. Also since I use PC time to time, I may feel more comfortable with 950H in the long-run. Finally the 150 nit 100% brightness of OLED sounds a bit restrictive during daytime.
The part where I cannot make my mind is on the viewing angle and reflections/glare. I've seen both TVs several times, and noticed the following ... A8H and all OLED use very glossy screen, and at the "right condition" the reflections are much more "clearer" and noticeable than LED TVs.. On the other hand on the "right condition", the 950H has strange rainbow that is mildly distracting.... Overall, I feel during daytime, I would probably be less distracted by 950H's reflection as its less like a full mirror... This is kinda important for me as we don't like using curtains on our window for various reason.
The second part is on the viewing angle, and OLED is hands down far superior to anything on viewing angle (even IPS), vertical and horizontal.. It's clearly better, but I could "live" with 950H and even 900H (though I don't consider this model) was OK upto around 45 degree...
Would appreciate any current users feedback on my scenario before I pull my trigger (I'm torn between trying my first OLED experience ... or going for the more 'practical' 950H)
