@rdipardo
many thanks for your response!
In fact it is so that now, where i repeated the steps for to make an illustrative image, i have to notice that i was pretty sure to have (following the windows docs) tried
LoadImage(… , LR_LOADMAP3DCOLORS) as well as LoadImage(… , LR_LOADTRANSPARENT) as well as LoadImage(… , LR_LOADMAP3DCOLORS or LR_LOADTRANSPARENT),
but something must have been wrong here, because indeed the latter version does remove this ‘glow’ also.
The illustration:
the left image shows the example bitmap from the reference plugin, without regard if the plugin is loaded/active or not the correction using LR_LOADMAP3DCOLORS looks fully identical. But only if my plugin is not loaded. If loaded,it looks somehow like ‘focused’ (but not exactly the same) -> image in the middle. the right image shows how it would look only using LR_LOADTRANSPARENT.
With ‘LR_LOADMAP3DCOLORS or LR_LOADTRANSPARENT’ it looks again exactly like in the left image, without regard if the plugin is loaded or not; it’s all ok.
Please note, the reference plugin does use this combination only for the ICOs … Not for the BMPs.

To my interpretaton the ‘fluent’ images are an independent story, but i may be wrong here.
What i see is that for the plugin’s toolbar image the BMP is used, without regard of light or dark.
When being within Settings > preferences > general > standard icons: small.
The ‘fluent’ images (based on each an ICO for dark and light) come into play (imo) only when chosing the fluent UI items within this preferences, if i see right.
Edit: i missed to add an image for the original rendering, which had motivated this thread:
