Kind of misleading their quoting such high QE numbers. It needs to be an apples to apples comparison. So a mono QE figure obviously is what the sensor actually does.

A colour sensor is way less as its got a bayer or other array on top and that weakens QE a lot as you point out. So 35% is more likely a figure.

True Sense Kodak colour arrays are likely to be higher because they have some clear filters in there just like LRGB imaging uses.

One of the DSLR manufacturers also has that technology. I forget which one now.

If someone is planning to get one shot colour then realise it will be a fraction of the sensitivity of the mono. Probably something like 1/2 or less sensitive. Due to the maths used to calculate the values of surrounding pixels it isn't 1/4 or less as it may seem but its a big hit to sensitivity.
