legacy = UIGraphicsBeginImageContextWithOptions + UIGraphicsEndImageContext

modern = UIGraphicsImageRendererFormat + UIGraphicsImageRenderer

Take aways:

"modern" w/ prefersExtendedRange = NO
- basically the same perf as "legacy"
- probably a good idea to adopt since optimizations will likely be in "modern" first
"modern" w/ prefersExtendedRange = YES

I have tried a lot of solutions for IP-camera streams.

Result: random crashes and not working cameras

Result: compile time error. I haven't successfully integrated it to my project.
