Canon R3 - Hot, Dead or Stuck Pixels

I have some of each on my new R3.

I had a bright white pixel in the same place in all images, but one of the suggested Manual Cleanings seems to have removed that. But it caused me to test further.

I am using an accurate, but no longer available utility to test and measure luminance and position of all the errant pixels. Called Dead pixel test. I also view CR3's at full screen, 100% and pan the images to see the visible pixel issues. I test at ISO's 100, 200, 800, 1600, 3200, 6400 and 12800. And at 1/30th, 1 second and 2 seconds for a good sampling. Interesting that the worst issues are at ISO 3200.

I am confused as to how a dead pixels can appear in only some ISO's and/or some shutter speeds. I would think if truly dead, then would show at all combinations. But it appears at ISO 100 I have none yet worst case (worse than ISO 12800) ISO 3200 2 seconds I have 7 Dead and 87 Hot pixels. At one second 4Dead and 50 Hot.

So question is: Realizing that "some" amount of maybe hot pixels is inevitable, how many is acceptable on a $6K camera?

And, will mapping all of this be excessive if I expect to be able to use images for large prints and monitors?

Have you tested your R3 for pixel issues?

I have been talking with Canon, but not getting enough information for me to decide how to proceed. I do have the camera schedule to go in to service, but concerned about mapping this amount of pixels and further, I am assuming only the "dead" pixels can be mapped and not the hot pixels and whether I will have confidence in my shoots.

Would appreciate opinions and even stats if you have tested your R3's. Thanks.

Thanks all.

Some raw files would be nice.

Thanks. Too many to share. And what it would show is a stuck white pixel or group of pixels in the same spot at "most" ISO's and shutter speeds.

Dealing with Canon. Went in for service. Original stuck pixel group remapped but a new one in a new area created and shown in first shot when returned from service. I think too many, in my opinion. Sure, hot pixels expected, but not stuck white. Camera still shy of 400 shots.

So, not getting data on how many or what kind are too many to expect or whay and how some higher ISO / Longer Shutter SPeeds can have less noise, I am left to what I think should be the performance for a new expensive camera.

Choose a few then. Say four.

Here is prior history so that we can see what has been tried already:
