Like most things, there's a law of diminishing return for sure. And calibrating the projector is definitely more about refining the image than fixing a problem.
Did I love the picture the first time I fired up the 5050? Oh, HELL YES! I was blown away. So "need" may not be the right word here.
That said, is there room for improvement? Yup. No doubt. Epson even had their 6050 calibrated for the NYC launch event and kept the calibrator on hand for the evening.
Towards the end of my calibration, I sat with Chad (hdtvbychadb.com) as he was putting the finishing touches on and asked him to show me what he was tweaking.
We had on The Greatest Showman and it was an outside, dark scene where people were carrying torches. Chad was trying to nail down the skin tones. He was going back and forth on a single adjustment in the 8-point greyscale settings. Never in a million years would I have thought that I could see the difference if the Grey Scale Level 5 Green was a -2 or a -3. But when Chad showed me what to look for during the changes, it suddenly became very easy to see the differences.
Some other projector review site shared three calibrations for HDR "best", HDR "bright" and SDR. Its worth just looking at the data and seeing the differences between them. (projectorreviews.com/epson/epson-home-cinema-5050ub-4k-capable-home-theater-projector-review-calibration-settings)
For a look at some of the data, take a look at the attached graphs. These are some of the pre/post calibration reports. In graph form, it looks like a pretty dramatic difference. Whether or not someone can see the differences, or think they are significant, or think its worth the extra money are personal choices.
When I think about the amount of money I've invested in my movie watching experience, an extra $500 to squeeze out additional performance from the projector seemed like an easy decision to make. I think of it the same way as treating a room for 2nd and 3rd level reflections, or painting the ceiling a dark color to improve the contrast on the screen.
Just my $.03. Curious what you think of the graphs,
