I'll challenge the frame of the question.
"Truly love" as in hollywood is a fictitious license / artifact for entertainment purposes.
Real love is a different thing for each relationship. Some are paternal, come protective, some dependent, some mutual admiration, some are a kind of deeper friendship, some companionship, some complicated shared pasts, some sexual/physical, some a form of idealization... And of course, mixes of all those. As you can see, many of these may be considered "shallow". But you can deepen any of those a lot and would be considered real. The one feeling them will at least consider them very real. But some of those, in the deep form, are considered harmful or toxic from the outside. Both are real, the shallow versions and the ones felt strongest. They are real because they exist, and they define behaviors.
Like stones are real, without having anything other than determinism defining their characteristics and behavior.
You may have seen some form of love different from the one you experience, and being a form of love that you have not experienced, may be thinking that the other one has some quality that yours does not have and that makes it more "pure" or "real", but oh boy.
The real versions of hollywood "love" (too sexual, too based on idealization of relationships and too hormone based ) end pretty fast, badly, with someone pretty broken, and many times a kid(s) eating what's left.
You experience real love. That it lacks some quality that you have seen from the outside on other loves does not make those more real or yours less. Mind that the outside is usually the best that the participants allow to publicly surface; all relationships have complicated pieces dancing under the surface, and many of those pieces are the closest to determinism and instinct that you can get.
