There is no content for 5k yet. YouTube & Netflix have only limited 4k. So why the need for 5k? I'm thinking that it would be unused unless you're doing photo editing. Other than that it appears to be a waste. Logically you would want a 8k display as the next jump for future proofing. I have a 4k Samsung TV which is outstanding! But 5k hits me as odd. (Pun intended). Why did Apple go that route?
