Does Google giving more important to internal pages than homepage recently? Especially after the recent Major algo update?

Hi everybody,

I can see the change Google brought in the SERP. Previously website homepages will be shown for primary keywords, now it's slowly and almost switched to showing most related internal pages in a website. You can check same for keyword "SEO", Most or all the results are internal pages. I can see this change for our primary keyword from last one month. So basically Google is trying to show a page explaining about the primary keywords rather than website, that's how "what is seo" pages are ranking than homepages. If there is no such pages existed or not well written, Google is just showing the website homepage. But I noticed that websites ranking with homepages are dropped compared to the websites with dedicated page about that primary keyword. Please share your thoughts.

Thanks
