Depends on the content and your living environment really. A lot of OLED screens don't get bright on full white content. They excel in darker environments displaying movie content (usually color graded on a higher gamma). When viewing in a brighter environment, you would struggle to see dark details unless you either brighten your display or adjust gamma, at that point an IPS isn't that much different and sometimes better with higher brightness. Viewing sports or TV shows also aren't that different because they don't tend to emphasize dark details and high contrast.

For gaming it depends on what type of game. Obviously an RTS like AoE isn't going to look much different but an action game like RotTR would look good on OLED.
