I want to know the answer to the following question:
In what areas are comb filters most likely to lose detail?
All the background I'm provided with is that "Depending upon which format is used, this can result in far higher fidelity, particularly at strong color borders or regions of high detail (especially if there is moderate movement in the picture) and low-contrast details like skin tones, where comb filters almost inevitably smudge some detail.". Is that enough to answer the question?
Answer: yes
