With that much LED light I would be concerned about the high blue peak around 450 nm, it's damaging the retina.

That paper pretty much just proved that blue light is more damaging than other colours. That would be expected, it is higher energy. Only the amount of light energy per area at the bottom surface of the cage was measured. It was unclear exactly how diffused the light source was. That would be important because the lens of the eye would focus all the light on a small area of the retina. To relate this to a human lighting situation you would have to specify the light energy per area at the light source. People normally will not tolerate bare point source LEDs for lighting. They are diffused in practice.

You can all but get rid of that peak if you're willing to pay for really high CRI LEDs. Check out these for example https://www.waveformlighting.com/high-cri-led
