There has been tremendous progress in terms of available calories, malnutrition and deaths to starvation globally [0]. I'd say opaque indices and relative measures are now gaining adoption by certain parties to help conceal that fact. Of course anyone suffering hunger is tragic, but things have decidedly improved (although sadly it has plateaued in Africa since 2010).
I can't really comment on the situation in India specifically, but just for some global context around stunted development, look at a chart of men's height [1]. Not having half your population stunted by malnutrition is a recent phenomenon.
Your first link says that it measures calories available and not calories consumed. It links to an undernourishment metric instead the world average for it has remained about the same for about a decade. I am not expert and I am probably cherry picking the page that matches my bias but I disagree that the progress has been tremendous.
> but I disagree that the progress has been tremendous.
There really is no argument that it hasn't. If we take a year between 1950 and 1970 as a baseline, there was a significant reduction in chronic malnutrition and the number and severity of famines -- both in absolute numbers as well as per capita.

If your time horizon is the last 10 years then the picture is more mixed, yea.
