Chromis - identification help

[Mac01]

I recently purchased a Chromis and I noticed these red/brown spots around forehead and eye. They are on both sides.

Can anyone indicate if this is normal or potential disease?

Pictures attached.

Thanks

If they are more of less symetrical on both sides, that looks like it could be head and lateral line erosion, HLLE. Rare, but not unheard of for green chromis to get this.
