ID 526593 - A warning message that isn't user-friendly appears when setting the Gamma View Transform slider to its lowest value

Problem summary:
A warning message that isn't user-friendly appears when setting the Gamma View Transform slider to its lowest value

Customer reported version
Mari 7.0v1

Customer reported platform
Windows 10 

Steps to reproduce:

1. Launch Mari and open any project (tested with nuke-default OCIO)

2. In the View Transform Toolbar, drag the Gamma View Transform slider to 0 

Expected behaviour:
There should be no warning message.
Alternatively, the warning message should be clear and relevant, such as: "Setting the Gamma setting in the View Transform Toolbar too low can turn the View black. Consider setting it closer to 1"

Actual behaviour:
A warning message appears, which is difficult to relate to the Gamma View Transform:

Failed to build display filter due to the following error(s):
LegacyViewingPipeline is not valid: ExponentTransform validation failed: Parameter 100 is greater than upper bound 100
This may cause differences in colors and it is strongly recommended that the error is corrected before proceeding.
 

If the Gamma is set too low, and the user doesn't realise this, the View will show as black, and the user won't know why.

Workaround:
No known workaround.
