Histogram overexposure accuracy?

Is something not working like it should? Let us know.

I'm getting very different results in Pixelmator versus Apple Pages for the RGB histogram specifically when it comes to the point where pixels are clipping/overexposing. The Pages histogram shows pixels clipping at a certain point--and I trust it because I can see the clipping right at that point. Pixelmator seems to show significant headroom still remaining.

Possibly related: if a 10% bump to exposure in pages brings a certain picture to the point of overexposure, it seems to be more like a 70% bump in Pixelmator. Maybe those percentages mean something very different in the different software, but I would have thought for something as simple as exposure the number means directly what it says it means.

If possible, could you share a few examples illustrating these differences? Or, if you don't wish to post them on the forum, you can send them to us by email to support@pixelmator.com and we'll take it from there. Thanks!
