No, it's sorta kinda like "more perfect" as ideal and perfect are closely related and often used in the same sense such as: an ideal choice or a perfect choice. Since forums are too often reduced to petty and long drawn-out disagreements over the meaning or correctness of words, let's put this to rest now because it's easy. This minor controversy arose from Nikon's statement: "Although this method [HE/HE* (High Efficiency) compressed] uses a non-reversible algorithm similar to compressed mode, the result is a smaller file size while maintaining the same quality [as compressed mode], effectively making this more ideal solution."
The use of "more ideal" is not simply nonsense. You absolutely can compare things to words representing standards like ideal and perfect — in fact, they are words which invite comparison. I previously provided a link with examples of writers using "more ideal" and I'll share a couple of those examples, but let me start with a well known use of "more perfect" first, simply because it's so well known: We the People of the United States, in Order to form a more perfect Union — the beginning words of the U.S. Constitution. Below are samples of the use of "more ideal" (something which is closer to an ideal form, state, model, etc.) from the link I provided:
"Still the Politicus contains a higher and more ideal conception of politics than any other of Plato's writings." — Introduction and Analysis to Statesman by Plato
"Probably no composer has ever had more ideal circumstances for artistic inspiration and expression than had Orlando." — Encyclopaedia Britannica, 11th Edition, Volume 16, entry for composer Lasso (Lassus), Orlando [Orlande de Lassus]
There are numerous examples of "more ideal" contained in writers' works spanning centuries, but this little episode of let's mock Nikon for their choice of words is long past its bedtime and should be gently rocked to sleep. 😴
You can investigate the use of "very unique" on your own here if you're interested. 😏
