mmmh you should expect that life always reduces a planet's albedo then, and if you're looking for planets that host life, check out those that have atypically low albedo for their chemical composition [now with fixed screenshot, source: twitter.com/mwgkgk/status/]

life might have it easier to arise on bright planets because those have a larger albedo gap, carbon planets might paradoxically be bad places for life (spitballing here: would a planet with homogenous albedo be more likely to be a desert? think Venus, Mars, Uranus)

then again, consider a plant with bright leaves that it has for cooling; it's not a complete refutation but it does make matters more complicated
