That’s exactly it. Also happens with a lot of lights on the Death Star.
I can’t say if it is in their print or not, but I just had a look at one of mine, and I adjusted it (very sloppily, not worrying about colour and blowing out the whites to try and force any bleed to show) to be at a similar contrast level, and the print I have here doesn’t appear to have the smearing.
Just curious but how did you adjust it? 😃
