There are a couple of meanings or senses we have of the word objective and subjective
In the Ontological sense (ie what there is to know in the universe), we have both objective facts and subjective facts.
There are facts of the material world we understand in physics, chemistry etc.
There are also the facts of subjectivity from conscious creatures.
"Whats its like to be you in this moment?" ...It has subjective facts, underpinned by objective facts about your body and your brain.
We can talk about human subjectivity objectively in the Epistemological sense.
Take for example the phenomenon condition Tinnitus.
Tinnitus is a physical condition, experienced as noises or ringing in the ears or head when no such external physical noise is present. Tinnitus is usually caused by a fault in the hearing system; it is a symptom, not a disease in itself.
We know it's real and not imagined.
We know what kind of inner ear damage can produce it.
We can study it from subjective facts (subject can tell if it's a high frequency or low frequency ring, or even the exact tone)
There should be no impediments to us studying Tinnitus, or ANY other subjective experiences we have, such as those experiences with DMT.
Unfortunately yes, we have to rely on self report to some degree to study these things. We know that sometimes people aren't the best judge of their moment to moment experience. People who have been manipulated into thinking certain things via neuro linguistic programming techniques, will often give different reasons for why they came to a conclusions, yet we know why they did.
Its worth worrying about this when trying to design specific experiments, but this is not a fundamental epistemological problem that rules out understanding of this in scientific terms. And if it does, then that would rule everything out about science of the mind. It would rule out anything to know about depression, schizophrenia, anything in neuroscience and psychology, because these things are subjective experiences.
