Projects are darker after update from Resolve 16 to 17

Hello!

After updating from Resolve 16.2 (also tried other versions) to Resolve 17.1 (also tried 17.0) the graded footage in my projects became darker. You can also see it in the scopes, that there is a down shift.
I also tried to export the project in Resolve 16, created a new database in 17 and imported the project there, but the graded videos are still darker.
Is this a known issue and does anyone know a solution to this?

Cheers,
Armin

I did some further testing. I deleted all nodes in a project which got darker after the update and added only one node with basic grades. With this one basic node the project did not get darker. It seems like at least one node with more complex grades behaves different in Resolve 17 than in Resolve 16. It requires some further extensive testing to find that node.

I did even further testing. It seems like this issue is happening with pretty much every node.
In conclusion:

- When I have just one node in a grade, where I only correct the gamma and darks, the scopes are identical in Resolve 16 and when updated to Resolve 17
- As soon as I add some further correction of any kind, the grade looks different (mostly slight brightness shifts) when updating to Resolve 17

Can anyone confirm this issue?

I haven't noticed any such differences in my own projects. But I also never do all the work in one node. I would not expect that to make any difference, but maybe if there's a bug...
