Why is this happening? Color change from another software to PS??

This is actually spawned from another thread. While working with this thread I came upon this and it is kinda blowing my mind. I'm sure there is a logical explanation, please give it to me.
While doing an experiment for the thread about CS5 corrupting colors, I made a file in Paint Shop Pro 5 and it is this one. This was saved as a Tiff and in the sRGB color space.

Then I opened this Tiff file in Photoshop CC and Photoshop CS6. Note that this file looks totally different. Why?
Test2 PSCC.JPG
 
To me it looks like a transparency issue
 
I'm on and iPad only thing I see is percentages are different but not that much, how about colors is one set to pastel?
 
That file was made with PSP equivalent to PS Gradients, I made another one with PSP and just did some simple fills and they look OK in PS.
My values, sampling a 1 point sample at 0,0 is 255,176,178. What do you get?
 
The colors in the next file don't match either. They look OK visually, but upon sampling they are not the same...what tha heck???
 
Also check off use all layers I see thats not same
 
There's not but one. Background only
 
Upload the tiff file then we can see it I dont have paint shop installed anymore to try and duplicate it myself
 
I am going to say it is the color conversion taking it from a 24 bit image to an 8 bit image can you not change the bit depth on paintshop export or export as another file type. But yes seems very weird that ps does not recognonise the true depth of it

oh and the only thing I can see is that it is putting it up 2 stops in exposure so when you import it in adobe camera raw just move the exposure from +2 to 0 and you should get it back. regardless of depth and format. But I have no idea why adobe is trying to auto correct exposure on tiff
 
"But I have no idea why adobe is trying to auto correct exposure on tiff".

I'm on my phone, not at my computer, so I can't easily check this, but I'm pretty sure one can set that as one of your preferences for how ACR behaves. :-)

My faith is restored! It works for me too. Weird deal there..what if one were not using ACR? It never occurred to me to make an adjustment in ACR although I open every Tiff and Jpg with it before taking into PS.
