That pattern of darker yellow urine coloration which improves with water intake does seem consistent with dehydration. This is a link to a study done specifically to answer the question of using urine color to indicate hydration status: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4949298/. Essentially, they found a relationship between urine color and daily fluid intake. Best wishes.
