Oh, it will look just fine on a 4K screen too.
The root problem is DPR Forums are full of people with too much time and too much disposable income. That's why we see these ad-nauseaum discussions of whether Irident is better than Lightroom or Lightzone, or whatever, and how if you are not adjusting your images in PS, you are not making the best out of your expensive camera. 99.9% of the time its not the post processing that's at fault. If someone wants to spend hours getting the foliage right on a boring shot, be my guest, but please don't sucker other people into thinking that if you use the latest and greatest niche RAW developer their photos would magically appear so much better. No. they won't! If you improve per-pixel sharpness of a cr&ppy photo, its still a cr&ppy photo. Its a peculiar disease of the digital age, people doing professional level treatment on mediocre junk.
Yes, every workflow is a compromise, just pick something that fits your style. But keep in mind that every hour you spend transferring files from Irident to Photoshop and then back to something else is time that you cannot spend shooting, or being with your family. And you don't do your equipment justice by post-processing the images for an hour, you do it justice by getting out and shooting good pictures hat tell a story, and that capture the feeling of the moment. Unfortnately, pixels at 200 percent carry no feelings, otherwise DPR Forums will be full of prize-winners every day.
P.S. BTW, Instagram has democratized image processing to the extent that no one is particularly appreciative of your photoshop skills anyway...
