Persuade me to go ultra wide fam

Yooo guys been waiting this one out for a while and found a solid deal locally on a low hour DWF. I know this is a solid monitor but I have two things holding me back. I have full capability of playing in 4k so should I spring for a 4k? Is it really worth the extra dollar? And also should I just go ultra wide?! I really like my current multiple monitor setup pictured below but I’ve been getting into more single player titles and love high FOV. How annoying is it really to have black crops on games that don’t support it??? Please list all pros and cons you can think of that would differ my current set up. Thanks in advance for any thoughts and opinions!
