"Auto-calculate W channel from RGB" appears to be ignored for last output

[marcone]

What happened?

The value of the "Auto-calculate W channel from RGB" options for each of the defined outputs determines whether the "Colors" tab shows a color wheel or not, but it appears this is ignored for the last output in the segment.

To Reproduce Bug

• define 4 "PWM White" outputs
• set the "Auto-calculate W channel from RGB" option for the first output to "Max", and for the other 3 outputs to "None"
• save and go back to the Colors tab, and note that the color wheel is shown, as expected.

But if instead of the first one, you set the LAST one to Max, then the color wheel is NOT shown.

Expected Behavior

Since all of the outputs are in the same segment, it shouldn't matter which output has the "Auto-calculate W channel from RGB" set to "Max". If any one of them has it set that way, the color wheel should be shown.

Please provide JSON status & info message from WLED for different configuration. Use your browser for that, developer tools, network tab.

Not sure what exactly you mean by "JSON status & info messages", but I've attached the response for /json/si after setting it to Max/None/None/None (which shows the color wheel), and after setting it to None/None/None/Max (which does not show the color wheel).
All 4 outputs work either way, but the UI is different for those two cases.
