In a Platonic ideal sense, they are the same. The concept of IV being a very "pure" idyllic concept. (Since no one can predict the next 70 years of any business, I don't care what it is and who you are.)
In reality -- in practice -- I have made a useful, non-blurry distinction.
Growth focused investors are primarily looking to benefit from the growth in the intrinsic economic value of the company over time, as measured by whatever KPIs you'd choose - cash flow, earnings, revenue, margins etc.
Value focused investors, from the early days, focused a great deal more on determining today's fair economic value and trying to buy the stock at much lower than that number, and sell it when it got close to that number.
The way the style indexes do it is pretty much nonsense - low P/B ratios and that kind of thing.
But I think there is a real difference between the two above and my experience lately has been that many have soured on the discount-from-value approach (as I've described it) and many more have chosen the ride-the-economic-growth approach.
You can, of course, find a hybrid strategy - but acknowledging that pretty much confirms that there are two (or more) things to hybridize.
